![]() There are now two 'backends' of device plug/unplug events, and there is about to become three. Rather than just adding two more vfuncs for every backend type define common ones that all providers can use. Also fix up the existing in-tree plugins to use the new vfunc names and filter on the correct GType. |

MSR
Introduction
This plugin checks if the Model-specific registers (MSRs) indicate the Direct Connect Interface (DCI) is enabled.
DCI allows debugging of Intel processors using the USB3 port. DCI should always be disabled and locked on production hardware as it allows the attacker to disable other firmware protection methods.
The result will be stored in a security attribute for HSI.
External interface access
This plugin requires read access to /sys/class/msr
.
